Belarus: Menestrels

This is a very nostalgic card for me. It's actually a note card, it was issued in Soviet Union in 1988. I used to collect postcards and note cards in my childhood and I remember having this one. I think the illustration is great and very unusual for Soviet times.
The sender pointed out that there is a typo on the stamp. The stamp is  to comemorate the Battle of Grunwald in 1410, but the stamp states it happened in 1500. However I think that 1500 is the price of the stamp in Belarusian money.
